Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during repairs.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly before raising the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper bolts with a socket set and lift the caliper off the rotor. Support it with a wire or bungee cord to avoid stress on the brake line.
Sub-step 2: Remove the old brake pads from the caliper bracket.
Sub-step 3: Inspect the caliper for proper movement; replace if necessary.
Sub-step 4: Install new brake pads by sliding them into place on the caliper bracket.
Sub-step 5: Reattach the caliper over the new brake pads and tighten caliper bolts to the manufacturer's specified torque (usually around 25-30 Nm).

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are worn or warped, remove them by unscrewing the retaining screws and sliding them off the hub.
Install new rotors and secure them with retaining screws.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts to the specified torque (typically around 120 Nm).

6. Final Check

Reconnect the battery.
Pump the brake pedal a few times to seat the brake pads.
Test the vehicle for proper brake function before returning to normal operation.
